WIND OW-PANE FASTENER.

To all whom 'it may concern:

13e it known that I, JosEr Grimm?, a citizen of thc United States, residing at Everett, in the county of Snohomish and State of Tashiugtou, have invented new and useful Improvements in lVindow-Pane Fasteners, of which the following is a specification.

'lhis invention relates to improvements in fastening strips for window panes and has for one of its objects the provision of a device of that kind, whereby a pane of glass may be secured in the sash of a window without the employment of putty.

Another object is the provision of a fas Lening strip formed of a single piece of sheet metal or its equivalent bent into such shape that when applied to the sash of a window it will correspond to the angle between the glass and inner side of the sash and present a neat and attractive appearance.

A further object is the provision of a fas tening strip integrally provided with barbs or the like, the said barbs being so located that the strip may be secured to the sash in an expeditious manner.

' A still further object is the revision of a packing strip preferably fiirmed of a springy substance and insertible between the inner face of the fastening strip and adjacent surfaces of the ane and sash, whereby the barbs may be driven into the sash to the required depth without danger of breaking the pane.

With these and other objects in view, which will more fully hereinafter appear, the present invention consists in certain novel details of construction and arrange ment of parts, hereinafter fully described, illustrated in the aceompan ing drawings and more particularly pointe out in the appended claims; it being understood that various changes in the form, roportion, size, and minor details ofthe device may be made, within the scope of the appended claims, without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings, formin a part of the specification;-Figure l is a pim view of a portion of the blank from which my improved device is constructed. Fig. 2 is a sectional end view ap roximately on the line 2 2 of Fig. 1 after t e blank is folded. Fig. 3 is a view similar to Fig. 2 but show- Specication of Letters Patent.

ing the fastener applied to a window sash and pane. Fig. 4 is a detail perspective of one end portion of the fastener.

Similar numerals of reference are employed to designate corresponding parts throughout.

The device about to be described is formed of a single piece of sheet metal corresponding in length to the pane receiving rabbet of a window sash. A portion of the blank or sheet is illustrated in Fig. l wherein-itwill be seen that the sheet 5 is oblong in contour and has a formed integral with one of its longitudinal sides a plurality of spaced barbs G. Prior to shaping the sheet to the angle formed by the inner side of the sash and pane, the sheet is bent upon itself longitudinallyT and at. its medial portion, whereby Sides 7 and S are provided, after which the outer side 7 is, at its medial portion bent outwardly and at right armies as shown at 9. It might here be stated that the barbs 6 are combined with the longitudinal edge of the inner side 8 and are perpendicular to the outwardly bent portion 9. By reference now to Figs. 2 to 4 inclusive.I it will be seen that the outwardly bent portion 9 terminates in a marginal flange l0, and adj aeent to the juncture of the sides and S the metal is bent at right angles, whereby a flange l1 is formed overhanging the inner side member 8 and extending in a direction at right angles to the direction of the flange 10. Reference to Fig. 4: discloses the fact that the barbs 6 project considerably beyond the plane of the longitudinal edge of the flange 10, thus permitting the barbs to enter a wooden sash until the edge of the fiange bears on the said sash.

By reference to Fig. 3 it will be seen that the inner surface of the strip formed by the side portion 8 and inner surface of the laterally bent portion 9 is provided with a cushion or packing strip designated in general by the numeral 12. This cushion or packing strip may be formed of rubber or by a mixture of glue and pulp and is shaped to the inner surface of the fastening strip. The thickness of the packing strip corresponds approximately to the width of the flanges 10 and 11, so that when positioned as shown in Figs. 2 and 3 the barbs 6 will extend through the strip, while the opposite sides will bear on the inner surfaces of the flanges l0 and 11. Yith this construction it w1ll be manifest when the flange 11 bears on the surface of the pane 13, as shown in Fig. 3 and the barbs G move into engagement \vitl1 the sash that the barbs may be driven home by applying a suitable tool to bear on the laterally bent portion 9 and then hammering the tool in a well-known manner.

From the foregoing it is evident that I have provided a device which is comparativeljr simple in structure and inexpensive in 1m1nufacture, embodying few parts and these so arranged that the danger of derangement ivill be reduced to a minimum.

I claim l. A fastening strip for window panes comprisingr a metallic plate bent upon itself at its lnedial portion and in the direction of its length to provide opposite side members one of which is bent laterally at its medial portion and terminates in a lateral flange, the said side members adjacent t0 their juncture being? bent laterally to provide a flange extending in a different direction to the first-named flange, in combination with a packing strip arranged over one face of the plate thus formed with its Opposite sides bearing on said flanges.

2. A fastening strip for \v1ndo\v panes comprising a metallic` plate bent. upon itself at its medial portion and in the direction of its length to provide opposite side members one of which is bent latex-all)y at its medial portion and terminates in a lateral flange, the said side members adjacent to their juncture being bent laterally to provide a flange extendingr in a ditlerent diret-- tion to the first-named flange, in combination with a packin T strip arranged over one face of the plate thus formed ivith its opposite sides bearing on said Hangers, and a pluralitjY of spaced barbs formed with one of the side members and projecting through the said packingr strip and extending parallel with the first-named flange.

In testimony whereof I aflix my signature in presence of two witnesses.
